A field observer on the code field.
Then, in the controller, you retrieve the object from db and then update
the page using rjs, like:

render :update do |page|
page[‘name’].value=your_object.name
page[‘price’].value=your_object.price
…
end

Now i am confused with the observer, should look like this?

:item_codigo = field with the data i received
:update => ‘articulos’ = is the div where is my field
get_X_code = mehod on my controller

<%= observe_field(:item_codigo,
:frequency => 0.5,
:update => ‘articulos’,
:url => { :action => :get_X_code},
:with => “‘codigo_id=’+escape(value)”)%>
??

In your view:

<%= observe_field(‘item_codigo’,
:url => { :action => :get_X_code},
:with => “codigo_id”) %>

No :update option is needed, since response is RJS

In controller:
item=Item.find_by_codigo_id(params[:codigo_id])
render :update do |page|
page[‘item_name’].value=item.name
…
end
